A model study on movements of sodium ions in pork loin during brining was carried out using (23)Na-magnetic resonance imaging ((23)Na-MRI). Samples of different pH and post-mortem age were mounted in Plexiglas(®) cylinders with built-in phantoms and cured in 18.9% and 18.1% NaCl (w/v), respectively. One-dimensional (23)Na-MRI and apparent diffusion(More)
Eight pork loin samples were mounted in Plexiglas cylinders and cured for five days. Samples were scanned by computed tomography (CT) once every 24 h. At the end of the experiment, the cylinders were cut in 1 cm sections and analyzed for chloride. From image analysis of the CT images, concentration profiles were extracted and fitted to a diffusion model(More)
Furan, a potential carcinogen, has been detected in highly consumed starchy foods, such as bread and snacks; however, research on furan generation in these food matrixes has not been undertaken, thus far. The present study explored the effect of ascorbic acid addition and cooking methods (frying and baking) over furan occurrence and its relation with the(More)
The results obtained by insemination with 3,418 frozen donor ejaculates with known semen characteristics were analyzed. The concentrations of motile spermatozoa before and after thawing were significantly higher in samples from donors producing pregnancies compared to samples from donors not causing pregnancies. In ejaculates known specifically to have(More)
Commercial refrigerating systems need to be defrosted regularly to maintain a satisfactory performance. When defrosting the evaporator coil, the air temperature inside the display cabinet will increase, and float outside the normal temperature range for a period of time, the question is what happens to the food inside during this period, when we look at the(More)
Semen for use in artificial insemination must be of good quality. To satisfy this demand we have to be able to predict the quality of semen from individual donors. Statistical analyses of data on 3,418 ejaculates from 87 donors demonstrated that each donor's ejaculates could be characterized by a lognormal distribution of the sperm concentration, the(More)
